Bonjour Pau1m, I'm not a programmer but I could understand what this is about and correct me if I'm wrong; this contract lets you deposit a donation into it and then splits it to whatever percentages you specify into two or more addresses. If that was the case, I think it's super valuable for content creators on platforms like Youtube to collaborate with one another and split payments without relying on copyrights laws and middlemen. I like to educate people about Ethereum and this contract can be used as a demonstration of how dapps can revolutionize the way we exchange value with one another. Can you please help me run it on my device? What tools do I need? I'm a bit familiar with truffle and ganache. Which of these 'gists' should I download? Thanks in advance :)
